The main user flow is essentially unchanged: logged out users are free to browse reddit’s content but are prompted to log in or create an account in order to participate.

The main changes you’ll notice in this patch:

Less clutter and fewer words. These windows have been reduced to the minimum needed text for easier readability.

Bigger targets. Buttons and form elements are easier to hit for quicker use, especially on mobile devices (see Fitt’s Law)

Explanations, not just alerts. We’ve tried to make errors more understandable so users know what’s gone wrong. For instance, if users try to create a username with only two letters, the alert will say “username must be between 3 and 20 characters” instead of “invalid username.” If they try a name that’s already taken, they’ll see “that username is taken” instead of “try another.”

We’re experimentally removing CAPTCHA and using other methods for spambot detection. We know it’s annoying for humans, and are starting to worry the bots are actually enjoying it. Plus, our visual CAPTCHA was failing on accessibility for non-visual redditors.

This looks awesome! Re the captchas, have you lot seen/experimented with invisible captchas? See https://github.com/stevenbristol/less-reverse-captcha – it’s invisible to humans and only visible to bots, so it offers the opportunity to catch evil-doers without bothering actual people.
